Description
Technical Field

Background
Welding is a manufacturing process and technique for joining metals or other thermoplastic materials, such as plastics, by heat, high temperature or high pressure. Consumable electrode gas shielded welding is a welding method in which an arc generated between a welding wire and a workpiece is used as a heat source to melt metal. In the welding process, a molten pool and a welding area formed by the arc melting welding wire and the base metal are protected by inert gas or active gas, so that the harmful effect of ambient air can be effectively prevented.
The welding wire used in conventional consumable electrode gas shielded welding naturally has a certain radian, and meanwhile, the welding wire also has a spiral, which can cause random swing of the welding wire, and the welding wire causes arc deviation during welding, and the arc deviation influences the forming and performance of a welding seam during welding.

The conducting rod is driven by the rotating mechanism to rotate positively and negatively, the rotating speed and the positive and negative angles are controllable, and the length of the conducting rod can be selected according to the thickness of the welded steel plate so as to ensure that the conducting nozzle can penetrate into the bottom of the welding seam; the special conducting nozzle with the deflection angle theta is fixed at the end part of the conducting rod, so that the welding wire which extends out of the conducting nozzle after passing through the conducting rod forms deflection with a certain angle, therefore, when the conducting rod rotates, the end part of the welding wire forms an arc swing taking the center of the conducting rod as the center of a circle, the movement range of an arc at the end part of the welding wire is enlarged, and the two side steel plate walls of the welding seam can be directly fused and fused into the welding seam under the action of arc heat.
This patent document has the following disadvantages: the deflection angle theta value of the contact tip is fixed, and the deflection angle formed by the welding wire after the welding wire extends out of the conductive path is also fixed, so that the arc swinging range of the arc at the end part of the welding wire is unchanged. When the arc swing range of the arc at the end part of the welding wire needs to be adjusted, the contact tips with different deflection angle theta values need to be replaced, so that the replacement and disassembly of the contact tips are time-consuming, and the operation is inconvenient; and no inert shielding gas supply scheme is disclosed, and the end of the welding wire is easy to be subjected to the harmful effect of surrounding air due to the expansion of the movement range when the welding wire swings in an arc shape.
